TOOL-HANDLE.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed Qctober 1S, 1919. Serial No. 831,071.

To all whom it mag concern Be it known that I, LAzARUs S. Hoop, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Tool-Handles, of which the following is a specification.

This invention relates to improvements in handles for tools of various kinds, such, for example, as screw drivers.

The object of the invention is to provide a hollow metal handle structure including a tool carrying shank in such a novel manner that fewer parts are required than heretofore in structures of this character, resulting not only in decreased cost of manufacture but also in a handle structure in which strength and durability are combined with lightness and simplicity of construction.

With the above and related objects in view, the invention consists in the novel construction and combinations of parts hereinafter described and claimed.

In the accompanying drawings illustrating the invention,-

Figure 1 is a top view of a tool handle embodying my invention, the same being illustrated in connection with a screw driver.

Fig. 2 is a side view thereof.

Fig. 3 is a longitudinal section through the handle.

Fig. 4 is a view similar to Fig. 3, with the securing rivets removed and one of the handle members slightly spaced from the other.

Pig. 5 is a transverse section through the handle, on line 55 of Fig. 2.

Referring to the drawings 2 and 3 designate two handle members, and t a tool shank on which may be formed any desired tool, such as the screw driver 6 illustrated herein.

The members 2 and 3 extend side by side longitudinally of the device, and each member forms substantially one-half of the handle proper. The members 2 and 3 are arched in cross section, as illustrated, and they have opposing chambers 7 and 8, respectively, formed therein, and they engage each other around the said chambers, generally on a plane extending centrally through the edge of the handle, and thereby form a hollow handle, as clearly illustrated in the drawings.

The members 2 and 3 are each preferably formed of a single steel forging, and the tool shank l and its tool 6 are included in the forging which forms the handle, so that the entire device, exclusive of means for securing the handle members together and inclusive of the handle members 2 and the shank t and the tool 6 are formed of but two pieces of metal.

The handle members 2 and 3 are secured together by two spaced rivets 9 which extend through the chambers 7 and 8 and through the walls of the members 2 and 3 and which are riveted in countersunk holes in the members 2 and 3. Preferably, the rivets 9 are provided with shoulders 10 which engage the inner faces of the members 2 and 3 and support them against being crushed in wardly. The provision of the shoulders 19 also strengthens and stiffens the entire handle structure.

The tool shank 4: extends laterally from the handle member 3, forming a shoulder 11 which abuts against the adjacent end of the handle member 2, thereby strengthening the structure and increasing the durability thereof, particularly when the tool carried by the shank 4: is driven against an object by blows struck against the opposite end of the handle members 2 and 3, and when the handle members and shank are used as a pry bar. The end of the member 2 which abuts against the shoulder 11 also is seated within a groove or ofiet in the shoulder, thereby embracing a part of the shoulder 11 which thus prevents lateral displacement of the members 2 and 3 relatively to each other.

I claim as my invention 1. A tool handle comprising two longitudinal handle members, each being arched in cross section, providing chambers in opposing sides thereof, each member having an endless edge portion entirely surrounding every dimension of its chamber and engaging the edge portion of the other member, and means for securing said members together, one of said members having a tool shank extending therefrom, one of said memhere being formed of a single steel forging, and the other of said members and said shank being formed of a single steel forging.

2. A tool handle comprising two longitudinal handle members each being arched in cross section, providing chambers in opposing sides thereof and engaging each other around the edges of said chambers and thereby forming ahollow handle, one of said members having a tool shank extending therefrom, and means for securing said members together, said shank extending on opposite sides of the longitudinal center of the handle, one of said members and said shank being formed of a single steel forging, and the other of said members being formed 10 of a single steel forging and terminating in close proximity to said shank.

In testimony whereof I aflix my signature hereto.
